The first examples of covalent organic frameworks (COFs) were discovered in 2005, but quality has been poor and preparation methods uncontrolled. Now researchers have produced high-quality versions of these materials, demonstrate their superior pr...
Water is one of the most fascinating substances on Earth and at the heart of its many unusual properties is high polarizability, a strong response to an applied electric field. Now researchers have found that on a microscopic scale water behaves v...
A team has solved a major fabrication challenge for perovskite cells -- the intriguing potential challengers to silicon-based solar cells. The team reveals a new scalable means of applying the compound PCBM, a critical component, to perovskite cells.
Scientists have developed a portable, shareable light sheet microscope. The project can be mailed to a lab anywhere in the world, configured remotely by engineers, and run one to three months of experiments.
Researchers have developed a graphene assembled film that has over 60 percent higher thermal conductivity than graphite film -- despite the fact that graphite simply consists of many layers of graphene. The graphene film shows great potential as a...
The UK's first energy-positive classroom generated more than one and a half times the energy it consumed, according to data from its first year of operation, the team has revealed. The findings were announced as the researchers launched the next p...
A scientist says the natural evolution of social organizations into larger and more complex communities exhibiting distinct hierarchies can be predicted from the same law of physics that gives rise to tree branches and river deltas -- a concept ca...
Researchers more than doubled the ability of a material to convert heat into electricity, which could help reduce the amount of wasted heat, and thus wasted fossil fuel, in daily activities and industries.
Abrupt changes of wind power generation output are a source of severe damage to power systems. Researchers have developed a stochastic modeling method that enables to evaluate the impact of such phenomena.
The same researchers, who last year designed a tiny computer chip tailored to help honeybee-sized drones navigate, have now shrunk their chip design even further, in both size and power consumption.
(Massachusetts Institute of Technology) Scientists at MIT and elsewhere have analyzed data from K2, the follow-up mission to NASA's Kepler Space Telescope, and have discovered a trove of possible exoplanets amid some 50,000 stars. In a paper that ...
(ESO) Astronomers using the ESO Very Large Telescope, and the NASA/ESA Hubble Space Telescope, have made the most precise test yet of Einstein's general theory of relativity outside the Milky Way. The galaxy ESO 325-G004 distorts light from a gala...
(University of Surrey) A team of international astrophysicists may have found a solution to a problem that has perplexed scientists for more than 50 years: why are the stars in globular clusters made of material different to other stars found in t...
(NASA/Goddard Space Flight Center) Southern Texas and the western Gulf of Mexico is getting a soaking because of a low pressure system. The Global Precipitation Measurement mission or GPM core satellite passed over the western Gulf of Mexico and m...
(NASA/Goddard Space Flight Center) A storm of tiny dust particles has engulfed much of Mars over the last two weeks and prompted NASA's Opportunity rover to suspend science operations. But across the planet, NASA's Curiosity rover, which has been ...
(University of Colorado at Boulder) Researchers at the University of Colorado Boulder have helped to find the last reservoir of ordinary matter hiding in the universe.
(NASA/Goddard Space Flight Center) Beneficial rainfall from hurricane Bud's remnants has spread into the US Desert Southwest after making landfall in western Mexico and moving north. NASA added up the rainfall using satellite data to provide a ful...
(NASA/Goddard Space Flight Center) NASA Terra satellite captured an image of Tropical Depression Carlotta as it was making landfall in southwestern Mexico where it weakened into a remnant low pressure area.
(Johannes Gutenberg Universitaet Mainz) Theoretical physicists from Maint and Stanford calculate the origin of a high-energy particle track captured by the IceCube Neutrino Observatory.
Climate change will have a rapidly increasing effect on the structure of global ecological communities over the next few decades, with amphibians and reptiles being significantly more affected than birds and mammals, a new report finds.
Palm oil has become part of our daily lives, but a recent study serves as a reminder that intensive farming of this crop has a major impact on the environment. Both short- and long-term solutions exist, however. The article analyzed the carbon cos...
While 2018 marks the centenary of the death of the last captive Carolina parakeet -- North America's only native parrot, a team of researchers have shed new light on the previously known geographical range of the species.
What stops a species adapting to an ever-wider range of conditions, continuously expanding its geographic range? A biomathematician now explains the formation of species' range margins. The theory shows that just two compound parameters, important...
Climate change, pesticides and land use changes alone cannot fully explain the decline in insect populations in Germany. Scientists have now discovered that regions that have experienced a sharp decline in flying insects also have high levels of l...
Local conservation actions can significantly boost coral's resilience to, and recovery from, climate-induced thermal bleaching by reducing other energy-sapping stresses the coral faces, a new study finds. Scientists found they could reduce the ext...
Researchers argue that the world needs more diverse, ambitious and area-specific targets for retaining important natural systems to safeguard humanity.
